如何将字符串解析为数组

Question

If a have a string in this format:

$parsethis = 'string[1][2]';

How do I parse it so my result is an array like:

$parsed = ['string', 1 , 2]

Answer 1

You can do something like this:

var $parsethis = 'string[1][2]';
var arr = $parsethis.replace(/\]/g,'').split('['); 
//arr = ["string", "1", "2"]
alert(arr); //alerts "string,1,2"

The arr array will be all strings, though. Based on the question, I do not know how you will be using the results.

Answer 2

You can get an array from that string using str.split(), and then cleaning it up with str.replace().

var parsed = parsethis.split('['); 
console.log(parsed); // ["string", "1]", "2]"]
for(var i = 0; i++; i<parsed.length){
  parsed[i] = parsed[i].replace(']','');
}
console.log(parsed); // ["string", "1", "2"]

Answer 3

I think REGEX is the way to go here, in compiination with the Arrays split method.

var array = $parsed.split(/\]\[|\[|\]/);

console.log(array) results in
Array [ "string", "1", "2", "" ]

iam not very good at using regular expressions, but maybe this is leading you in the right direction.
